What is the measure of one side?
A square is a quadrilateral with four equal sides that has four angles that are equal and two diagonals that bisect each other at 90 degree.
Area of a square = length of a side²
length of a side = √ area
√180 = 13.42

Answer:
0.973
Step-by-step explanation:
Solution
I'm going to discuss one way to do it, and then show a much better way.
If you attack the problem directly, there are 3 ways of placing just 1 day not being late
0.7 * 0.3 * 0.3 = .063
0.3 * 0.7 * 0.3 = .063
0.3 * 0.3 * 0.7 = 0.63
Making it on on time on two days gives you 3 equations as well
0.7* 0.7 * 0.3 = .147
0.7* 0.3 * 0.7 = .147
0.3 * 0.7 * 0.7 = .147
Making it on time all three days
0.7 * 0.7 * 0.7 = .343
If you add add these up, you should get 0.973
There is a better way. First calculate what happens if he is late all three days.
0.3 * 0.3 * 0.3 = 0.027 No on times (.7) anywhere.
If you take 0.027 away from 1, you get 0.973 That takes care of all the times he was on time. Much neater and easier, no?

Move a number or variable to each line to create the expression.

Explanation:
Has three termscoefficient of 5constant of 8Move numbers or variable:
y + 5x + 8
Additional Information:
x + y + 1
This has three terms, coefficient of 1, constant of 1
Answer:
[tex]\huge\boxed{\bf\: x + 5y + 8}[/tex]
Step-by-step explanation:
We need to make an expression using the given conditions. Let's look at them in order.
Condition 1:
If the expression has three terms then let's take the three terms as, x, y & z. Therefore, the expression uoto now = x + y + z.
Condition 2:
Now, the expression has a term with coefficient = 5. Let's put 'y' with coefficient 5 since the second term has two blanks in the question. So, expression = x + 5y + z.
Condition 3:
The expression also has a constant 8. By substituting the value of 'z' with 8 (as 'z' is not given in the options), we get the final expression as → x + 5y + 8.

Answer:
C) 20.97 AED
Step-by-step explanation:
To find the expected value, E(X), or mean μ of a discrete random variable X, simply multiply each value of the random variable by its probability and add the products. The formula is given as [tex]\displaystyle E(X)=\mu=\sum xP(x)[/tex].
Here, x represents values of the random variable X, [tex]P(x)[/tex] represents the corresponding probability, and symbol [tex]\displaystyle \sum[/tex] represents the sum of all products [tex]xP(x)[/tex]. Here we use the symbol [tex]\mu[/tex] for the mean because it is a parameter. It represents the mean of a population.
In this case, the expected value of the ticket is [tex]\displaystyle E(X)=\mu=\sum xP(x)=12(0.08)+18(0.15)+20(0.31)+22(0.08)+24(0.15)+25(0.23)=20.97[/tex]
This means that Ahmad can expect to win 20.97 AED for the ticket.

which of the following rational functions is graphed below?
The graph represents the function (D) because the graph of the function is not defined at x = 1 and x = 2 option (D) is correct.
What is a function?It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
We have a graph of a function:
If we take the function:
[tex]\rm f(x) = \dfrac{1}{\left(x-1\right)\left(x-2\right)}[/tex]
At x = 1 and x = 2 the function will be not defined, so this region would be hollow and as we can see in the graph of a function.
The function is not defined at x = 1 and x = 2.
Thus, the graph represents the function (D) because the graph of the function is not defined at x = 1 and x = 2.

A company offers its employees free recreational activities and gym memberships. of the 200 employees, 95 employees registered for recreational activities, 80 employees registered for gym memberships, and 30 employees did not register at all. if an employee is chosen at random, what is the probability that the employee has registered for both recreational activities and gym memberships?
a.) 39/40
b.) 3/20
c.) 17/20
d.) 1/40
From the calculation, we can see that, the probability that an employee has registered for both recreational activities and gym memberships is 1/40.
What is probability?The term probability refers to the chance that an event will occur or not. The probability of an event always lies between zero and 1.
Given that;
Number that registered for recreational activities = 95
Number that registered for gym membership = 80
Number that did not register at all = 30
Total number of gym employees =200
Hence; 95 + 80 +30 =205
Number that registered for both recreational activities and gym membership
= 205 - 200 =5
The probability that an employee has registered for both recreational activities and gym memberships is; 5/200 = 1/40

Answer:
Step-byThe equation of the line with slope 2 is y=2x+b, b is a constant which should be determined. The line passes via through points (1, 2) and (3,y)
(1, 2): 2=2+b --> b=0
So, the equation of the line is y=2x. Now, when x=3, y=6. So the line y=2x passes through points (1, 2) and (3, 6). (3,y)=(3, 6).-step explanation:

Determine the justification for the steps from the derivation of the quadratic formula. justification of step a: justification of step b:
The justification of step a is common denominator and the justification of step b is multiplication property of equality
How to determine the justifications?The equation is given as:
[tex]a(x + \frac{b}{2a})^2 = -c + \frac{b^2}{4a}[/tex]
Take the LCM
This gives
[tex]a(x + \frac{b}{2a})^2 = \frac{-4ac + b^2}{4a}[/tex]
The above represents a common denominator.
Multiply both sides by 4a
[tex]4a^2(x + \frac{b}{2a})^2 = -4ac + b^2[/tex]
The above represents the multiplication property
Hence, the justifications are common denominator and multiplication property of equality
